The Warm Springs Natural Area, also known as the Warm Springs Ranch, is located near the Moapa Indian Reservation in Clark County, Nevada at an elevation of 2,123 feet (647 m). The 1,179-acre (477 ha) area is owned by the Southern Nevada Water Authority (SNWA). The area is a natural oasis in the Mojave Desert. The oasis is fed by close to 24 natural warm springs and contains many naturally occurring California fan palms (Washingtonia filifera), creating an ecosystem normally limited to the "low" Colorado Desert and so unique to the "high" Mojave Desert. The springs are the headwaters for the Muddy River.
